To all whom t mag/concern.'

Be it known that we, IRA MAIER and FLORIAN KoLENo, citizens of theUnited States and Austria, respectively, and residents of the city ofNew York, in the county ofv New York and State of New York, have.invented certain new and useful Improvements in Cooking Stoves, of whichthe following is a specification.

The present invention relates to improvements in cooking stoves, andmore particularly to stoves employing gaseous fuel.

One of the objects of the invention is to provide a stove of the typementioned with water heating means,lthe hot water being adapted to beused for any suitable purpose.

Another object of the invention is to so construct the stove that with asingle burner or a single set ofburners cooking utensils on the top ofthe stove, a broiler compartment and an oven compartment are adapted tobe efficiently heated. at comparatively low cost. I Y

A further objectV 4of the invention is .to

so-design `the stove thatits top, broiler coml partment and ovencompartment may be either heated simultaneously, or either one ofsaidtwofcompartments may be cut out,'or bothv compartments may besimultaneously closed to :render l.theburners inoperative in relationthereto; inA any one of the cases mentioned, however, heat-is suppliedtothe water heating means. r v

kA still further object of the-invention is to provide acooking stove ofthe type mentioned rwhich is ysimple in construction, eficient inoperation durable in use, capable of manufacture on a commercial scale,or in other words one which is not so difiicult t0y make as to bebeyondthe reasonable cost o such a contrivance. y -With these and otherobjectsginv view, which will more fully appear as the nature of theinvention is better understood, thev same consists in thecombinationarrange ment and-construction of parts hereinafter described,pointed out in the appended claims and illustrated in the accompanyingdrawings, it being 'understood that -many changes may beimadein the sizeand proportion of the several parts and details of construction withinthe scope of the appended claims, without departing from the spirit orsacrificing any of the advantages of the invention.

Two of the many possible embodiments of the kinvention lare illustratedin the accompanying drawings, in which Figure 1v is a longitudinalcentral section taken through a stove constructedin accordance with thepresent invention, part of the same being shown in elevation; Fig. 2 isa sectiontaken on line 2 2 of Fig. 1, on a larger scale.; Fig. 3 is asection similar to the oneshown in Fig. 1 of a portion of a modifiedstove; Fig. 4 is a top elevation of the modification shown in Fig. 3;and Fig.

5 Yis a top elevation, showing the use of a hot water container and asteam table in connection with the stove. l

Referring now first to Figs. 1 and.2 of the drawings, ythe stove framecomprises two closed casings 10V and 11, the casing 11 belngconsiderably higher than the casing 10. Thecasing 10 is adapted to bedivided into two compartments, denoted by the numerals 12and 13, by ahorizontal partition 14, the

said partition 'being shiftable in guides 15 on theinner faces ofthesides of the compartment 10. `The partition is provided with a handle16, 'disposed outside of the' casing ,10,r by which handle it may -betaken holdjof and movedin and out of the casing. 10, fora Vpurpose.hereinafter to be described.'v the end wall 17 of the' casing -,10"areuprovided openings 18, and in alignment with the said openings thereare provided. in the-.opposite vend wall 19 of the casinglO openings-20,the casing 10 communieating with the'casing 11 through thelastmentioned-.openings I The compartment 12 constitutes the burnercompartment,v the burners being in the form of two horizontally disposedipes 21, which extendthroughout the lengtli of the compartment 12 andterminate in the end wall 22 ofthe compartment 11. These pipes arespaced, as clearly shown in Fig.-2 of the drawings, andare each providedwith-v in, the :compartment 12with two or more rows Vof perforations 23,through which the gas issues in the yform of jets, the gas 1nterminglingwith air as it enters the pipesl 21 througha mixing chamber 24A on eachthe pipes. through a supply pipe 25, asusual in constructions of thistype, the communisoY 4of the said pipes. l.The gas is conducted to n terpipe 27, the said water pipe entering the compartment 12 through one ofthe openings 18 in the side wall 17 thereof and leaving the stovethrough the end wall 22 in the compartment 11, the water being heated ina manner hereinafter to be described and conducted to a storagereceptacle and steam table, as will hereinafter appear.

Above the openings 2O in the end wall 19 is disposed in the casing 11 ahorizontal partition 28, which is shiftable in guides 29- pans, or othercooking and baking utensils,

not shown in the drawings.

In the top 33 of the compartment 30 is provided a plurality of openings34, controlled by a shutter 85, in the form of a disk. rllhis disk isattached to a spindle 36, which extends slidably through a yokeshapedguide 37. lVhen the pressure within the compartment 30 exceeds a certaindegrec, the shutter is automatically lifted, p-ermitting the escape ofgases therefrom, the shutter dropping 'automatically on the top of thecompartment 30 when the pressurefis released. c f

The compartment 13, below the partition 14, is made use of for broilingpurposes. It hasvmounted within it a plurality of ledges or shelves 38,a pair of the same for supporting a. grill 39, and one of the same adrip-pan 40, as usual in devices of this type.

. y rlhe compartment 13 is provided with an opening 41, controlled,preferably, by a sliding door 42, the said door being mounted invertical guides 43 on the end wall 17 of the casing 10.

The casing 11 is furthermore provided bei low the openings 2O with afixed horizontal partition 44, whereby a compartment 45 is obtained, towhich access may be had through a door (not shown). Within thiscompartment is provided a plurality of ledges or shelves 47 forsupporting pans or other baking utensils. In this compartment arearranged one or more burners 48, which are independent of the burnersabove described. I This last-mentioned compartment is made use of incase the stove is to be used for baking purposes only, in which case itwould only be a waste of-fuel if the entire stove were to be heated.

p rlhe burner lpipes 21 are disposed at a suitable distance below thetop 49 of the compartment 12. This top is provided with a plurality ofopenings 50, in which are dis- The operation of the stove is as follows:

Fuel being permitted to flow into the burner pipes 21 and the jetsissuing through the perforations therein having been ignited, the waterpipe 25 isy heated and at the same time the stove top 49. If it isintended to use the stove simultaneously for cooking, baking andbroiling purposes, the slidable partitions 14 and 28 are withdrawn fromthe stove, so that not only will the stove top be heated but also thebroiling and baking compartments thereof. Both the broiling and bakingcompartments may be cut off from the heat sources or either on-e of thesame, as required, by inserting both slidable partitions or either one,as desired.

The modification illustrated in Figs. 3 and 4 of the drawings differsfrom the one above described only in that, `instead of the burner pipes21, burners 52 are used, the latter beingin the form of substantiallyelliptic burner bodies 53, provided with perforations 54, through whichthe fuel issues. Otherwise the yconstruction and operation of theelements are the same as those described in connection with Figs. 1 and2 of the drawings.

`Figure `5 of the drawings illustrates diagrammatically the stove,denoted by the character S, in combination with a container 55 and asteam table 56. To the water pipe 27, as it leaves the stove, isconnected a Y-joint 57, one of the branches of the joint being connectedby a pipe 58 with the container, and the other branch of the Y-joint bya pipe .59 with the steam table. The steam table is .connected by a pipe60 with the container. In the pipe 25 is inserted a three-way valve 61.When the valve 61 is in its open position, the hot Water, issuing fromthe stove, flows both to the container' and into the steam table, itflowing from the latter into the container through the pipe 60.` Hotwater may be drawn from the container by means not shown. If it isintended to supply water to the steam table l the top of the stove, abroiler compartment and an oven compartment, either one or both of saidcompartments being adapted to be closed to render the burnersinoperative in relation thereto.

lVhat we claim is:

l. A stove including a burner compartment, 'a broiler compartment belowsaid burner compartment, means for opening or closing, at will, thecommunication between said two compartments, said burner compartmentincluding a top, and a burner within said burner compartment below Saidtop, said burner being adapted to heat said top and said broilercompartment when said two compartments arein communication.
